What is Kubernetes?
Kubernetes originated at Google, drawing on internal experience running containers at scale with systems like Borg, and was open-sourced in 2014. Google donated the project to the newly formed Cloud Native Computing Foundation (CNCF) in 2015, where it remains a graduated project governed independently of any single vendor.
Read the full overview
The system works by reconciling a declared desired state (which containers should run, how many replicas, what resources they need) against the cluster's actual state, restarting or rescheduling workloads as needed. It's extensible through Custom Resource Definitions (CRDs) and the operator pattern, which is how most third-party tools (service meshes, databases, CI/CD systems) integrate with it.

KubernetesContainers & KubernetesOpen-source container orchestration for deploying and scaling workloads
Key capabilities
- Scheduling: Place containers onto cluster nodes based on declared resource requests.
- Self-healing: Restart or reschedule failed containers to match desired state.
- Service discovery and load balancing: Route traffic to healthy pods.
- Extensibility: Add custom resources and controllers (operators) for domain-specific automation.
A useful evaluation deploys a real multi-service application, kills a pod and a node to confirm self-healing behavior, and checks whether the team's chosen networking and storage plugins meet actual production requirements.

Reviews of Kubernetes
Powerful but complex4/5 starsKubernetes solved our scaling and deployment challenges, but the learning curve is steep. It took our team several months to become proficient. Now that we have it running smoothly with ArgoCD for GitOps, it is incredibly powerful. Not recommended for small teams or simple applications though.
